A battered pink bag used by workers in baggage claim sparked a security scare at the Minneapolis-St. Paul International Airport on Tuesday, becoming the latest sign of these suddenly jittery times in airline travel.

For the meantime, travelers may just have to get used to it as the industry grapples with increased security in the wake of the failed Christmas Day attempt to bomb Northwest Airlines Flight 253.

“I think that we’re going to continue to have these scares — it comes with the territory,” said consumer travel expert Chris Elliott. “Everyone got jumpy after 9/11, then after the liquid gel scare. The same thing is happening now. Everyone is very jumpy.”

The 90-minute evacuation of parts of the Lindbergh Terminal came hours after an airport in California was shut down when suspicious material was found inside luggage. It turned out to be five soft drink bottles filled with honey. On Sunday, a man breached security at Newark Liberty International Airport, resulting in major delays and grounding flights for six hours.
